CHILICNEY CAP.

Application le September 16, 192.

To all fte/1.0m# may conce/rn:

Be it known that l, CHARLES B. WAeoNnR,

a citizen of the United States, residing at Rochester, in the county of Monroe and i State of New York, have invented certain new and useful improvements in Chimney Caps, of which the following is a specification.

My invention relates to chimney caps, and has for its purpose to afford a practical and durable construction adapted to be readily and firmly positioned on a chimney and to serve, in general. more satisfactorily than caps now in use for the same purpose.

w A more specific object of the invention is to provide a cap of minimum weight, so that it can be constructed economically and readily transported to wherever it is to be used.

A further purpose of the invention is to 2@ afford a construction which, while of light weight and simple construction, nevertheless lends itself readily to a firm, rigid connection with the chimney, so that it cannot be accidentally removed by high winds or otherwise.

Still an additional object of the invention is to afford a construction that accomplishes all of the purposes above set forth, and which also eifeetually prevents rain accumulating;

3l) on the chimney cap from reaching the side walls of the chimney underneath the cap, vthus preventing the side walls of the chimney from being streaked or discolored, and the mortar between the bricks from disintegrating, by water running down from the cap.

The invention also comprehends certain `other advantages and detailed improvements, all of which will appear clearly from -U the following description, in conjunction with the accompanying drawing, the novel features being pointed out in the claims Afollowing the specification.

Tn the drawing:

im `Figure l is a perspective view of a chimney. showing the application of a preferred embodiment of my invention, appearing partly in section, and

Figure 2 is a transverse sectional view through the chimney and cap.

'lhe device herein disclosed comprises an integral or one-piece cap adapted to rest upon the uppermost layer of bricks forming the chimney 1. The cap is preferably formed of glass, terra cotta, porcelain, shale clay, or other similar non-conducting material, pref-A Serial No. 501,118.

erably vitrified and glazed on its outer surface, and its walls have a cross sectional form `of' inverted lil-shape, consisting of the horizontal portion 2 and the depending legs 3 and d. This arrangement permits manufacturing cap of the required strength and efficiency, while at the same time of such light weight as to enable readily shipping or transporting it and placing it in position on a chimney.

Although chimney cap is usually attached by mortar, it is nevertheless essential that it be locked in place against lateral displacement, and to accomplish this, l provide a depending ilange, or flanges, 5 on the outer legs 4, and preferably coextensive with the outer surface of the cap. rlhe flange 5 is adapted to overlie the sides ofthe chimney, and thus, after it is once positioned` there is no chance of accidental lateral displacement of the cap, and its firm attachment to the chimney is assured. l

ln order to prevent rain passing from the cap to the side walls of the chimney, l provide in the lower face of the Hangs 5, a longitudinally extending centrally arranged drip groove 6. which is preferably semi-circular in cross section. The drip groove 6 catches any water that would otherwise find its way across the bottom of the flange 5, and traps it, so that such water falls to the ground from the groove 6 without reaching the side walls of the chimney. The life of a chimney is increased substantially by this construction, because there is little likelihood of water settling in and destroying the mortar between the bricks of the chimney. Moreover, the proper appearance of the chimney is preserved. as it cannot be discolored by dripping rain water.

The construction described is exceedingly simple and durable, economical to manufacture and can be readilv applied to any chimney, as the caps will be made in certain standard sizes to fit the different standard sizes of chimneys. Bv forming the cap hollow. and of inverted U-shape` l am able to obtain a very light weight structure, which is of tremendous importance in shipping and positioning chimney caps. and this arrangement also lends itself with great facility to locking the cap upon the chimney against lateral displacement, through the depending Yflange formed upon the outer leg of the inverted ll-shaped wall.

While l have described a specific ernbodin ment of the invention, the improvement is not limited to the particular details disclosed, but may loe modified in various respects without departing from the underlying' features of the invention, and the application is intended to cover any modifications coming within the scope of the invention and of the following claims.

l claim:

l. As an article of manufacture, a light weight one-piece chimney cap comprising' hollow walls of inverted U-shaped cross section, the legs of which overlie the top of a chimney.

2. As an article of manufacture, a lightweight one-piece chimney cap comprising hollow walls of inverted Uehaped cross section, the legs of which overlie the top of a chimney7 the outer legs of said walls having flanges which overlie the sides of a chimney and prevent lateral movement of the cap.

3. As an article of manufacture, a onepiece chimney cap comprising walls of inverted U-sliaped cross section, the legs of which are adapted to rest on the upper edge of a chimney, and a continuous flange adapted to overlie the sides of a chimney and prevent lateral movement of the cap, said flange having a longitudinally extending drip groove formed centrally therein.

ln witness whereof, I have hereunto signed my name.

CHARLES B. WAGONER.
